Got these 3 lines here and I have no clue where they go.

1) I have some BS aftermarket Boost Guage that came with the car when I bought it. That was connected to this (I think!). I removed it cause it sucks, but the line left over looks like it was there from the factory, so I'm wondering if there is something else that needs to fill its space. The boost guage had 2 lines going to it. This I'm almost positive was one, and I think either #2 or #3 were the other
2) Comes off of the oil/vacuum lines below the solenoid rack
3) Same as #2

Bump!

C'mon, someones gotta know. Even if you only know one post it up.

Thanks

number 2 and 3 go into the stock rubber intake hose between the air box and turbo, both of them should have metal pieces on the end like 3 does and one has a white dot on the hose which corrosponds with the white dot on the intake hose. number one looks like its one of the ones that come off the turbo. if number one comes off of the metal hose attached to the turbo then it goes to the angled metal nipple sticking out of the compressor housing, just below the hose between the turbo and intercooler. at least stock, i have no idea why it's so long. do not drive your car like that!!!! your waste gate will not open and you will get boost spike. i just had one of the other hoses on that break and it destroyed my turbo and i still can't get it to run.

Sweet, thanks!

Oh, and Im not driving my car, I'm putting the rebuilt engine in, so I'm trying to piece it back together.

no problem, good luck

1. Looks like the water hose from the back of the water pump. Goes to the water union attached to the front of the bac on a 87.

3..Goes to the duct that is inbetween the afm and the turo inlet.

2. Unknown. I think its 89 and up related. Probably boost control related. I dunnno.

Ok, #2 and #3 match up, thanks.

But im confused on #1. From what I read you are saying it connects to the tube coming off just below the intercooler pipe. But if you look in this pic, the other end connects to that. I need to know where the circled end goes.

AreExSeven

Nay on #1. On the S5, a electrical connector takes the place of that hose you are referring to. I know which one you are talking about as well.

Like I said before, I *USED* to have a boost guage that went into this line (I THINK!), but I removed it while I was pulling my engine. Now I need to know what I need to connect this line to, since it doesn't go to that anymore.

yearrgh

stock, that hose is about an inch and a half long, the uncircled end is where it's supposed to be, the circled end goes to an L shaped metal nipple that should be sticking out of the hole that's right under the black rubber piece that connects the hose between the intercooler and turbo. you also might want to put another clamp on the rubber thing where it connects to the turbo so you dont blow the big hose off

AreExSeven

Lol.
Should that L shapped nipple be here?

#1 is for your wastegate actuator that attaches to the intake manifold....forgot where thou..."it's been awhile".

yearrgh

exactly. i just switched my old waste gate actuator and turbine housing to a s4 turbo so i just dealt with connecting those on friday. 100% positive about this.

AreExSeven

Ok. So now that I don't have that little metal nipple, and I don't have my boost guage, what can I do with this line? Is it affecting my performance to have that little hole in the side of the turbo there (I would assume so)?

yearrgh

thats what puts pressure in the spring valve thingy that moves the wastegate actuator. if you don't get those connected, the wastegate will be stuck shut and you will get boost spike. i may have one of those extra from the old turbo, i gg to school now so i cant check but i'll be back by 3:00 and i'll let you know. if i find it i'd be happy to mail it to you

AreExSeven

Sweet, thanks a ton!

I was looking in the microfische, and it deosn't seem to have a part number for it, so I can't go order it.

yearrgh

i do have it. send me an email at yearrgh@aol.com and tell me where to mail it. it may take a day or to for me to respond to the email, i don't always check it.

AreExSeven

Man you are a saint!
I sent you an email

jmseven

That were it (#1) attaches to for vacuum...the nipple. Yours is missing......
